Electromotive double drive

Abstract

An electromotive double drive 2 for adjusting pivotally adjustable support parts of a support device for supporting a cushioning of a seating and/or lying furniture, in particular a mattress of a box-spring bed, relative to one another comprises a base body 4, at which two drive units 6, 8 are arranged, each comprising a drive member 10 or 12 respectively. The double drive 2 further comprises two pivot levers 18, 20 spaced apart from one another in longitudinal direction of the base body 4 and each pivotably disposed at the base body around a pivot axis 14 or 16 respectively, wherein the pivot levers 18, 20 are respectively in operative connection with the output member 10, 12 of an associated drive unit 6, 8 for pivoting the respective pivot lever 18, 20 relative to the base body 4. The base body 4 comprises two supporting and fixing structures 30, 32 spaced apart from one another in its longitudinal direction for supporting and fixing the base body 4 at transverse cross-members 38, 40, wherein each supporting and fixing structure 30, 32 comprises a support surface 34 or 36, respectively, for resting at a transverse cross-member 38, 40. According to the invention, the support surfaces 34, 36 are arranged in longitudinal direction of the base body at the height of the pivot axes 14, 16 in such a way that, in the mounting position of the double drive 2, the pivot axes 14, 16 lie in vertical direction via the respective associated support surface 34 or 36.
